I know these are a lot of vids in one time, but starting up a complete buildingthread will take too much time for me.
This weekend i'll want to make the maiden of the weather is ok, she's charging
up now for the event.

Thanks for the compliments, like every sub i build i always give my best shot at it, this type 212 sneaked through between building the type XVIIb.
Took some more time than estimated due to some technical adjustments, like i said before this weekend i'll take the plunge into the open water.

Ok, ok, i turned her a little bit inside out, it's a nice kit and adding some detail was a bit of a challence on this scale.
Re engineering the WTC was a differend story, the good basic layout was allready there, only had to add some items to get the system running the way i like it.

Yesterday i did the maiden, unfortunally something went wrong with saving the video's so i made a slideshow of the pictures, enjoy.

I've seen Chris his 212 on vid, it's pretty quick, from what i know from him she acts like a torpedo on full throttle.
I run mine with limited power and deflection on the rudder vanes, otherwise i can loose control at high speeds.

After the subsail i took her apart for adding some claws to this little critter, for now it seems that the second design is working, see for yourself.

Back on track with the type 212, she was on hold this summer because i had to do some things on my OSA II, last technical thing to do was, making the launchsystem work.

Replaced the filling hoses to the side of the breechblok, stuffed up the old hole at the back with some solder.

The complete set with the filling hoses and nipples, only problem with this kind of nipples is, in Europe you can't get the matching gasbottle for filling the torpedo's.
I decided to make some of my own, this way i can use standard butane lightergas.

First you take a lighter that you can refill, gently cut out the fillingnipple and rework it so it will fit into the new copper holder.

Just to show the difference between both nipples, mine i can use for butane gas.

Last step in rebuilding was, connecting the hoses to the fillingnipple and glue them tight to prevent leaking.

Also made some testtrails inside the shop to see if my modification would work.

Next step will be solving the airbubble problem which i encountered during underwater trails during the last meeting, i will take the tubes apart and make some slits, this way the air can escape out of the tube.
Then again i have to test if the problem has gone by doing testtrails in the bath tub, it keeps me busy.

Slowly i'm getting there, about the bouyancy, since you will fill up the torps totally with liquid gas they won't float, the torpedo will be replaced by the same amount of water after firing from the launchtube.
When the torpedo has released some gas it will start to float, no sooner.
This, in theory will not influence the balance of your boat, i only have to take account for the new position of the breechblock when fired, but it will reveal itself during the next testingstrails.

I spent some more hours inside the shop to solve some problems, fixed the leak, and tried another testrun in the bath.
Only made one attempt, and it worked just fine, now it's time to rebalance the boat and try some shots while being submerged.
